DEVICE FOR PREVENTING SINGLES IN DQUBLING AND SPINNING.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed November 3, 1906. Serial No. 341,879.

lb (LU 'uh om it may concern:

Be it known that l, lliin'm' Ninu'ris- GALE, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and usefulDevice for Preventing Singles in Doubling and Spinning.

My invention relates to improvements in doubling and spinning machinery in which two or more ends are run together; and has for its object the prevention of single ends running on the receiving spool when one of the other endsbreaks or a thread runs out. I attain these objects by the mechanism illustrated in the accompanying drawing; here toiore numerous devices have been designedv and applied with the. one object, namely ol stopping the spindle or spindles when one. end broke or run oll'. 'lhesc stop motions, for stopping the spindles when the thread breaks are usually very sensitive and intri cute, and are easily put out of order and fail to work causing single ends to run on the receiving spool which have to be unwound again causing waste and loss oi time. in my invention when one end breaks or runs oil' the ren'iaining end or ends are automatically broken and the spindles are left to run until they are again threaded.

Figure l is a front view of a spinning ma- Fig. 2 Fig. 3 is a plan view is a side view of Fig. l. V

Fig. 4 is an elevation of the two spindles. of the same.

Similar numeralsrefer torsimilar parts throughout the several views.

This drawing shows the spin, double and twist process in which the threads of the two spiinllesdoing the first time twisting run together and are received on a spindle giving The two spindles 2 having the spools 3 on them and revolving, twist the threads 8 which pass over rods 25 between which the l'allers l6 are held in position, as shown in Fig. 2 by the threads 8 passing through the eyes of same.

When a thread breaks the one taller falls to the position indicated by-the dot line 17. Supported near its center so t nearly balance it is another taller l? wh' has a short cross piece 14 at its upper 1 and another cross iece 11st its lower a The taller 16 when it falls back on account of an end breaking engages the taller 1.2 by

means oi" the said cross piece 14 and throws the piece 12 to the position 13 thus bringing the cross piece ll forward over the outside edge of the spool 3, this will cause the thread on the spool with the whole end' to break on account of the revolution of the spool and the pull on the thread as shown in Fig. 4.

As an auxiliary a knife. or shar piece of metal is or can be placed in a Slh e 23 and when the taller dro )S the end 20 pushes the metal of knife. 22 iorward so as to engage the thread 8 and the twist of the said thread severs it. Either of the devices can be used separately or together but the breaking oi the thread by the bar 11 is preferred Thus it can be seen that when one end breaks the other end will also be broken at the same time and each spool takesup its own end and no singles will run on the receiving spool as the are all pieced up together.

} aving thus described my invention what I claim and desire to secure by Letters Patent is:

l. The combination in a spinning and donblingmachine consisting of first. .i second time twistin spindles, the brac 19 su porting the roppcrs 16, through which t ie threads pass, the thread supporting rods 25 and the pivoted piece 13 consisting of an up- )er cross rod 14 and a lower cross rod 11, this latter rod beam thrown forward over and beyond the center of the spindles when thedro .per 17 falls back as set forth and described.
